(Cl. Sel- 124) 2 Claims.

My invention relates to textile treating or finishing and more particularly to steam heated drums or cylinders employed in ironing or drying machines, many of which are known in the trade as Palmer units.

One of the objects of my invention is to provide a steam heated cylinder for incorporation within a Palmer unit or the like and which is equipped with means for supplying steam in a manner to heat the outer peripheral wall of the cylinder together with means for removing water from the cylinder which is occasioned by condensation.

Another object of my invention resides in a method of fabricating a cylinder of the abovedescribed character in a manner to provide the same with a plurality of steam chambers defined by scoop partitions functioning to facilitate removal of the water.

An important object of my invention is to provide a cylinder of the foregoing described character which is simple in construction, eicient in operation, durable in use, economical in manufacture and capable of being installed in units already in use without substantial modification.

With the above and other objects in view, as will hereinafter appear, the invention consists in the combination and arrangement of parts hereinafter set forth and illustrated in the accompanying drawings from which the several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.

. Referring to the drawings wherein like reference characters designate like parts throughout the several views:

Figure 1 is an end elevation of a cylinder constructed in accordance with my invention.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a top plan view of the cylinder on a reduced scale with a portion of the outer wall being removed.

Figure 4 is an enlarged detail sectional view taken on the line li--II of Figure 3.

' As illustrated in the drawings, thereis provided a cylinder 5 comprising a pair of spaced shells defining cylindriform outer and inner walls 6 and 1, respectively, having their coincident ends connected and sealed together by radial end walls or bands 3 constituting the rims of spiders formed with hubs 9 connected to the bands by spokes. A pair of radially oppositely disposed partitions I0 extend longitudinally between the walls 6 and 1 and are connected to the latter 2 and the bands 8 to define a pair of steam chambers I I and I2, it being understood that thepartitions I Il are connected to the walls 6, 1 and 8 in a manner, for instance, by welding, to seal one chamber from the other.

The partitions it are longitudinally bowed between their ends to provide each partition with incurvated and recurvated side faces I4 and I5, respectively, as clearly illustrated in Figures 3 and 4 of the drawings. In spaced relation and in somewhat close proximity to the recurvated faces I5 of the partitions II), the inner wall 'I is provided with -centrally disposed openings in which are secured the outlet ends of supply pipes I6 whereby steam is supplied to the chambers II and I2, while in immediate proximity to the incurvated faces I4 of the partitions I0, the wall I is provided with centrally disposed openings in which are secured the inlet ends of drain pipes I'I to effect draining of water from the chambers, as hereinafter more fully described.

The hubs 9 have extending therethrough and in fixed relation therewith a hollow shaft I8 having its bore provided with a plug I9 intermediate the hubs 9 and which plug I9 functions to divide the shaft into steam inlet and water outlet conduits 2U and 2i to which are connected the inner ends of pipes I6 and Il, respectively, whereby communication is established between the conduits and the chambers I I and I2. The pipes I6 and I l, intermediate their ends, have incorporated therein flexible sections, for instance, hoses or the like 22 to facilitate connecting them between the chambers and the conduits 20 rand 2I.

The end sections of the shaft I 8 have fixed thereto, adjacent the hubs S, suitable collars 23 with one of the collars adapted to have keyed thereon a suitable gear connected to -a drive gear for effecting rotation of the cylinder, for instance, in the direction indicated by the arrow A. The end sections of the shaft I8 are also adapted to be mounted in suitable bearings and have connected thereto rotary unions eecting connection of the conduits 20 4and 2l with a source of steam supply and la siphoning or vnegative pressure creating apparatus, respectively. One of the end walls 8 is equipped with a pair of vacuum or negative pressure relief valves 24 for effecting communication between the atmosphere and the chambers II and I2, respectively, each of the valves operating in response to a predetermined pressure within the respective chamber whereby the pressure therein is maintained above a preestablished amount to preclude collapsing or distortion of the walls.

In operation, assuming the cylinder is rotated in the direction of the arrow A, steam is introduced into the chambers Il and I2 through the pipes I6 and conduit 20 and which steam serves to highly heat the wall 6 for drying and/or ironing textile material trained thereabout. As the steam condenses, during rotation of the cylinder, the water within the chambers will flow downwardly toward the lowermost partition and be siphoned therefrom through the adjacent pipe I1 and the conduit 2l, each of the partitions serving, due to its arcuate configuration, to direct the Water towards the center of the partition to facilitate draining of the lowermost chamber during rotation of the cylinder.

In order to facilitate the fabrication of the cylinder, particularly the installation of the partitions I0, the shell or outer Wall 6 initially corn- -prises a pair of semi-cylindrical portions which are assembled together about the wall 1 and between the walls 3 after the partitions i0 have been arranged and welded to the walls -1 and 8. `When the partitions i6 have been welded to the walls 1 and 8, one of the portions of the outer wall 6 is disposed over the walls 8 in spaced relation with the wall l and with one of its ends extending over and slightly beyond one of the partitions ID. When one portion is thus assembled, the end, extending over the partition, has itsunderface welded to the partition to securethe Vend in fixed and sealed relation with the partition, the opposite end of the portion 4being yleft free for outward displacement from the other partition vto permit the other portion to be similarly assembled and welded to the other partition. When the portions are thus welded to the respective partitions, their free ends are brought intorabutting relation'with and welded, as at 25, to their fixed ends, thereby, forming the continuous outer shell or wall 6, the latter, of course, being welded to the walls 8. By this novel method, I am enabled to provide the cylinder with a plurality of steam chambers for highly heating the outer wall and to utilize the partitions, which dene the chambers, as scoop partitions to facilitate drainage of Water occasioned by the condensation of steam within the chambers.

Without further elaboration, the foregoing will so fully explain the invention that 'others-may, by applying current knowledge, readily adapt the same-for use under various conditions of service. M'o'reovenit is not indispensable that all the 'featuresof the invention be used conjointly since theymay be employed advantageously in various combinations and subcombinations.

`It is obvious that the invention is not confined to Ythe herein described use therefore as it may -be utilized for any purpose to which it is adaptable. It is therefore to be understood that the inventionis not limited to the specific construction r`as illustrated and described, as the same is only `illustrative of the principles involved which'are capable of vextended application in various forms, and the invention comprehends all construction within the scope of the appended claims.

What I` claim is:
